I can't find a spec sheet for the HP motherboard you listed. However, if the processor is the same socket type as your current processor, then yes, the motherboard should still be compatible.
According to the spec sheets I was able to look up from Intel's website, the Intel I3 4150 and the I7 4790K both use FCLGA1150 sockets. So if you were able to use the former CPU on your current motherboard, then you should be good to go. Your current board should be compatible with the new CPU.
